Multi Sudoku

The application features 2,500 levels of varying difficulty. It includes both classic Sudoku and a multitude of multi-Sudoku variations, such as Samurai Sudoku, Triplets, Sohei, Butterfly, Tudoku, and others. Multi-Sudoku is a puzzle composed of several interconnected classic Sudoku grids, sharing common cells. Typically, on the intermediate and advanced levels, it is not possible to solve the individual component Sudokus separately; you must solve the entire puzzle as a whole. By revealing numbers in one Sudoku, new possibilities for eliminating candidates in others emerge.
